*
* Set @lossless %TRUE to switch to lossless compression.
*
* Use @compression to set the encoder e.g. HEVC, AVC, AV1. It defaults to AV1
* if the target filename ends with ".avif", otherwise HEVC.
*
* Use @speed to control the CPU effort spent improving compression.
* This is currently only applicable to AV1 encoders. Defaults to 5, 0 is
* slowest, 9 is fastest.
*
* Chroma subsampling is normally automatically disabled for Q >= 90. You can
* force the subsampling mode with @subsample_mode.
*
* See also: vips_image_write_to_file(), vips_heifload().
*
* Returns: 0 on success, -1 on error.

* * @dpi: %gdouble, render at this DPI
* * @scale: %gdouble, scale render by this factor
* * @background: #VipsArrayDouble background colour
*
* Render a PDF file into a VIPS image. Rendering uses the libpoppler library
* and should be fast.
*
* The output image is always RGBA --- CMYK PDFs will be
* converted. If you need CMYK bitmaps, you should use vips_magickload()
* instead.
*
* Use @page to select a page to render, numbering from zero.
*
* Use @n to select the number of pages to render. The default is 1. Pages are
* rendered in a vertical column, with each individual page aligned to the
* left. Set to -1 to mean "until the end of the document". Use vips_grid()
* to change page layout.
*
* Use @dpi to set the rendering resolution. The default is 72. Additionally,
* you can scale by setting @scale. If you set both, they combine.
*
* Use @background to set the background RGBA colour. The default is 255
* (solid white), use eg. 0 for a transparent background.
*
* The operation fills a number of header fields with metadata, for example
* "pdf-author". They may be useful.
*
* This function only reads the image header and does not render any pixel
* data. Rendering occurs when pixels are accessed.
*
* See also: vips_image_new_from_file(), vips_magickload().
*
* Returns: 0 on success, -1 on error.
